爲什麼Grails的未填充數據我有以下的引導類通過引導
import shoppingsolutionproject.Category;
import shoppingsolutionproject.Item
class BootStrap {
def dataSource
def init = { servletContext ->
new Category(description: 'Car').save()
new Category(description: 'Truck').save()
new Item(productNumber:1, name:"First Product", description: "This is the first product I'm adding for testing",
shippingCost: 4.99, url: '/first', retailPrice: 19.99, salePrice: 16.99, category: 'Car').save()
new Item(productNumber:2, name:"Second Product", description: "This is the second product I'm adding for testing",
shippingCost: 4.99, url: '/second', retailPrice: 19.99, category: 'Truck').save()
new Item(productNumber:3, name:"First/Second Product", description: "This is the first/second(so third) product I'm adding for testing",
shippingCost: 4.99, url: '/second', retailPrice: 17.99, category: 'Truck').save()
}
def destroy = {
}
}
當我啓動Grails的,雖然,我沒有做的類別或項目預先填充...任何想法,爲什麼?
很有可能您有驗證錯誤。驗證這一點的最快方法是將'failOnError:true'添加到'.save()'中,如下所示:'.save(failOnError:true)'。這應該會告訴你很多由於驗證錯誤而失敗的事情。 –
@JoshuaMoore你是對的,我使用字符串'Car'作爲類別而不是類別對象,我創建了 –
